The funniest moment in movie history? The Groucho Marx stateroom scene in "A Night at the Opera," right.

But maybe it's just me.

More than likely one of your favorite scenes will be up on screen during the Fort Lauderdale International Film Festival's two-day, 24-hour, 15-film Comedy-A-Thon at Cinema Paradiso on Labor Day Weekend.

From noon-midnight Sept. 5 and 10 a.m. to 10 p.m. Sept. 6, FLIFF will screen some of the funniest movies of all time -- from the Marx Brothers to "M*A*S*H" and Monty Python. Wil Shriner, comedian and director of episodes of "Frasier," "Everyone Loves Raymond," "The Gilmore Girls" and the feature film "Hoot," will kick-off each day with a montage of some of the great comedy moments ever.

For $15 ($10 FLIFF members) you can see all 15 films. Individual screenings are $3 ($1 members). For advance tickets, go to FLIFF.com or call 954-760-9898.

And how about this: Anyone who makes it through all the films on both days is eligible to win a FLIFF Fast Pass to the 25th Annual Fort Lauderdale International Film Festival Oct. 22 - Nov. 11. The Fast Pass (valued at $475) entitles you to attend all films and parties at the festival.
